Holy Roman Emperor Otto II is defeated by the Saracens in the Battle of Capo Colonna, in Calabria.

The Holy Roman Emperor, originally and officially the Emperor of the Romans during the Middle Ages, and also known as the Roman-German Emperor since the early modern period, was the ruler and head of state of the Holy Roman Empire. The title was held in conjunction with the title of King of Italy from the 8th to the 16th century, and, almost without interruption, with the title of King of Germany throughout the 12th to 18th centuries.

Otto II, called the Red, was Holy Roman Emperor from 973 until his death in 983. A member of the Ottonian dynasty, Otto II was the youngest and sole surviving son of Otto the Great and Adelaide of Italy.

The word "Saracen" was commonly used in medieval Europe to refer to a person who lived in or near what the ancient Romans knew as Arabia Petraea and Arabia Deserta. Its original meaning in Greek and Latin is not known with certainty. By the early medieval period, it had come to be associated with the Arabian tribes. Following the rise of Islam, which occurred in Arabia, the word's definition evolved to refer not only to Arabs, but to Muslims as well. It eventually became the standard adjective among European Christians for all people and things from the Muslim world, regardless of whether or not they were Arab in origin.

The Battle of Stilo was fought on 13 or 14 July 982 near Crotone in Calabria between the forces of Holy Roman Emperor Otto II and his Italo-Lombard allies and those of the Kalbid emir of Sicily, Abu'l-Qasim, who had declared a holy war against the Germans. Some sources claim that the Muslims received support from the Byzantines, in retaliation for Otto's invasion of their province of Apulia, but this is unconfirmed.
